IB Psychology IA: 60 Examples and Guidance

The International Baccalaureate (IB) program offers a variety of assessments for students, including Internal Assessments (IAs), which are pieces of coursework marked by students’ teachers. The Psychology IA is an assessment designed to test students' understanding of the material they have learned in their psychology course and their ability to conduct an experimental study.

What is the IB Psychology IA?

The IB Psychology IA is a project that requires students to conduct an original research study on a specific topic within the field of psychology. The IA must be based on empirical research, which means that students need to collect and analyze data to draw meaningful conclusions.

The investigation which students conduct will be executed as a group of 2-4 students, who work together on the research method, subjects and materials, as well as the operationalization of the Independent and Dependent Variables. However, the students will each write up the reports  independently of other group members, and the data will be analysed and conclusions drawn independently.

The report should contain an introduction, exploration, analysis, evaluation, and references.

60 Example Investigation Questions

Students should investigate an area which they are genuinely interested it. It can be from any area of psychology, but the theory or model on which the investigation is based must appear in a peer-reviewed publication. The link between this model and the students’ aims and objectives for their experiment must be made clear, as well as the relevance of the experiment. Here are 60 example investigation questions and descriptions. Some students choose to get the help of an IB Psychology tutor for extra support.

1. Does color influence cognitive recall in students?

Students could perform a quasi-experiment where they show two groups of students a list of words, with one list in black and white and the other list in vivid colors. The groups would then perform a recall task to determine which group remembers more words. This will enable students to examine the impact of color on cognitive recall.

How should I conduct the experiment?

The experimental method  looks for a relationship between the Independent and Dependent Variables, with all other factors being controlled as far as possible.

IB Psychology tutors note that it is crucial for experiments to have only one Independent Variable, which refers to the variable that is manipulated by the experimenters. Students should choose the number and nature of conditions for their experiment based on the study that informs their experiment. A simple experiment may have only two conditions for the Independent Variable, while the study that it is based on may have several. Students can replicate all the conditions or choose to simplify the experiment by selecting two conditions.

However, variables based on pre-existing characteristics of participants cannot be used for internal assessment. Examples of such variables include gender, age, native language, culture, education level, socio-economic status, and handedness. Although these variables might be interesting to students, they cannot be manipulated within the framework of the internal assessment. If any of these variables are defined as the Independent Variable, the experiment will not meet the requirements and will not earn marks.

It is also important to note that experiments involving placebos, ingestion or inhalation (such as food, drink, smoking, or drugs), or deprivation (such as sleep or food) are not acceptable and will not earn marks. The operationalization of the Independent Variable may differ from the original study, such as using different words for a word list or a different type of music, as long as the link between the study and the student's experiment remains clear.

The Dependent Variable is the variable that is measured, and there are various approaches that students can take when working with it. They can either replicate the operationalization of the Dependent Variable used in the study that their experiment is based on, or they can modify it to suit their own resources or circumstances. This can include altering the number or type of measurements taken or even selecting a different Dependent Variable altogether, as long as they can justify the link between their experiment and the original study.

Moreover, students may need to adjust the methodology of the study to better suit their working context. For instance, they may need to modify the nature of the participants, as the most feasible participants for a school experiment would likely be other students. Alternatively, they may need to alter the number of participants involved, as the original study might have had access to participant numbers that are impossible to replicate in a school environment. Similarly, the original study may have employed a matched pairs design, which is not feasible in school as there are too few participants to choose from.

The marking criteria have been designed to allow for a certain degree of flexibility, and students can earn full marks if they apply the aforementioned variations appropriately. Further assistance in conducting the experiment for internal assessment, as well as exemplars of student work, can be found in the teacher support material.

How should I analyse and evaluate the data?

Psychology tutors suggest that the analysis should include the descriptive statistics to highlight the variability and spread of the data, and inferential statistics to draw conclusions about the significance of the data generated in terms of supporting a hypothesis.

The evaluation should cover the limitations for the method and suggestions for improving the method to generate more data or more effective data in order to arrive at a firmer conclusion.

IB Psychology Subject Brief

What ethical guidelines should I consider?

Experimental studies that cause anxiety, stress, pain, or discomfort for participants are strictly prohibited. This also includes experiments that involve deception, conformity, obedience, or any other form of harm. It is important to consider the sensitivities of the school, community, and country when planning an experiment.

Unjustified deception, involuntary participation, invasion of privacy, and inappropriate use of ICT, email, or the internet must be avoided. If such infringements cannot be avoided, approval from experienced psychologists should be obtained before proceeding.

Partial deception may be allowed if it does not cause harm, and participants are fully debriefed at the end. Participants have the right to withdraw their data, except in conformity or obedience studies, which are never permitted.

Explicit consent must be obtained from participants using a consent form, and they must be informed of the aims and objectives of the experiment. Participants also have the right to withdraw at any time without pressure.

Children under 12 years of age cannot give informed consent, and parental consent is required for children from 12 to 16 years of age. Teachers' written consent is also required for school studies.

Participants must be debriefed, their anonymity guaranteed, and the results of the study shared with them. Local and international cultures must be respected, and participants must be in a fit state of mind to participate.

If a participant experiences stress or pain, the experiment must be stopped immediately, and they must be allowed to withdraw.

Non-human animals cannot be used for the experiment.

It is essential that all data collected during an experimental study is handled confidentially and with responsibility, without being disclosed to any third-party.

The data collected must only be used for the purpose agreed upon with the participants.

It is the responsibility of students to monitor their peers' research practices and encourage them to reconsider any practices that violate these guidelines.

The same guidelines apply to experimental studies conducted online. Any data collected online must be deleted once the research is completed and cannot be used for any purpose other than the experiment.

In cases where teachers require further guidance on the ethical implications of a particular experiment, they should consult other teachers via the OCC or IB tutors, who may offer additional expertise and critical perspectives.

Conclusion

In this guide, we've explored key steps for success in your IB Psychology IA. From choosing a topic to conducting research and presenting results, every stage is crucial. Remember, effective communication and a solid understanding of psychological principles are essential.
